Hello. I have a Samsung Galaxy S7 Edge. Last night I left my phone to charge with my Samsung fast charging adapter while my phone was 2%. It was plugged in for about 10 hours before i came to check on it in the morning. The LED light would not respond, none of the keys will respond to the phone and it just shows a black screen. Now what happens next is something that I have never seen before. 10 minutes after trying to solve the problem, a sky blue screen pops up with saying “press the up volume key to install and press the down volume key to cancel(restart)”. After seeing this I was hesitant to download it so I continued to press down and cancel. After not seeing any other possible solution I did press up and download it. I don’t remember what it said, but it was unfamiliar. I tried the many troubleshoot solutions like factory resetting or deleting cache but the phone will not respond in any way shape or form. — Antonio

Solution: Hi Antonio. Try to see if you can boot the phone to Maintenance mode. If it does respond and boots successfully, you may be able to restart the phone eventually back to normal mode. Below are the steps that you should try:

Turn off your Galaxy S7.

When powered down, press and hold the Power and Volume Down buttons at the same time.

Continue holding these two buttons until you see the special Maintenance Boot Mode Menu.

Let go of both the Power and Volume Down buttons.

If your phone remains unresponsive and only turns back on the current Download mode screen, you must then try to flash the bootloader back to stock. If that won’t work either, have the phone repaired or replaced.

For reference, here are the sample steps on how to flash a bootloader. Exact steps may be slightly different on your phone so make sure to look for a good guide online.

Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.

Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.

Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.

Proceed with the rest of the flashing procedure using the Odin program.

In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.

Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.

Restart the phone once the procedure is finished.

Problem 2: Galaxy S7 screen stays black, won’t show anything

Soft reboot works. It charges fully. I’m getting sounds and the digitizer works and haptic feedback. But i cannot get the screen to display anything. I can’t pull the battery because it’s an s7 and sealed and my glass would break if i pulled it apart. I’m pretty sure it’s the LCD that has failed but they are expensive. I’ve very tech savvy and have flashed Rom’s on other phones. Is there a way to get error codes or duplicate the screen on a computer to see what errors might come you. Any other solutions or help would be appreciated. Thanks. — Tyson

Solution: Hi Tyson. There’s no magic software solution to fix a bad screen. If the devices appears to receive notifications and shows indications that it’s turning on at this time, you have no other option but to send it in for repair. You can’t just plug it in and expect to be able to access the memory and do some software tricks to fix a malfunctioning screen assembly. If it’s under warranty, send it to Samsung and let them handle the screen replacement. Otherwise, let an independent technician replace the bad component for you.

Hi. My name is Kelsey. I have a Samsung Galaxy S7. I was in my pool taking pictures under water. When I do this i never put my ports under water. I always make sure to just put my camera under the water while holding my phone upside down. As risky as this is, i normally never have a problem. Well today my little cousin decided to blow water on me from his mouth and it got into my port. Not thinking anything of it, being the phone as water resistant, I just set my phone down. When I got to my charger later I plugged it up and it gave me the “moisture in port” message. I then took an air dryer to try and dry it off. ( I now know this is a really stupid idea). I then tried plugging it up and it gave me the “downloading do not turn target off.â€Then i believe it went completely dead again because that screen turned off. When i plugged it up for what felt like the millionth time it came up with the battery with the lightning strike in the middle. But when it was actually charging in the past, I had little green bubble like things blinking up to the display battery ( I hope this makes sense) .They are not popping up now. It is simply just the battery with the lightning strike. Does this mean I need to start looking for another phone? please tell me no. Thank you in advance! Sincerely. — Kelsey

Solution: Hi Kelsey. Using an air dryer is not really a bad idea in this case as long as you take care not to apply too much heat to the phone. A Galaxy S7 is water resistant and it’s supposed to alert its users not to charge if there’s traces of moisture in the charging port. As long as the system detects moisture in that part, the phone will not charge at all. This may be the reason why you are no longer able to turn it back on. The battery may have simply run out of juice at this time. Make sure to dry the charging port by gently shaking the device. If the phone will never charge after you’re certain that the charging port is now moisture-free, contact Samsung for a repair or replacement.

Problem 4: Galaxy S7 won’t connect to wifi, Home button not working properly

Hi! I have a Galaxy S7 and have had no issues until recently. Within the past week, I have had 3 issues:

trouble connecting to my Wi-Fi. I was able to solve this by turning on/off airplane mode several times.

pressing the home button creates a screenshot – this is still occurring and restarting the phone does not solve this. This happens intermittently

I keep getting a message out of nowhere to hold down the power button for several seconds to restart the phone.

I have not updated or installed any new apps. The phone says there is no update needed. I just find it odd that I have had 3 major issues in the past several days after not having any problems in the last two years. Thanks for any help you can give. — Alison

Solution: Hi Alison. If these issues appear out of nowhere, something drastic must have happened to the software or hardware. If your phone was exposed to water or elements, or was physically impacted after an accidental drop, bad hardware may be to blame. In this case, you would want to stop looking for a solution and simply have the phone checked. Only after a thorough physical check can a technician tell if repair will be able to fix the problems or not.

If your phone was never dropped or got wet before, do a factory reset and see what happens from there. If this is a software-related problem, your issues should not occur right after a factory reset (when there are no third party apps installed).

If the phone works normally after a factory reset but starts to act erratically after installing back your apps, one of them must be to blame. You must identify the problematic app using elimination process.

To factory reset your phone, follow these steps:

Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.

Turn off your Samsung Galaxy S7.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’

Once highlighted, you may press the Power key to select it.

Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.

Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

The phone will now reboot longer than usual.

Problem 5: Galaxy S7 can’t transmit sound in calls or text

Hello. I have an unlocked Samsung Galaxy S7 which I received from my brother and I am on the Freedom mobile network in Ontario Canada. A year or so ago when I received this phone I was quick to discover that it is not compatible with the wind mobile (now freedom) frequencies. I had to spend 30ish Canadian to have a man at a booth install a fix for this as nothing I tried worked (installing modem files etc). It worked fine for a while until one day my phone stopped allowing me to hear and transmit sound in phone calls or even messages. I have tested the microphone using Facebook messenger and voice recorder and it works just fine! I want to know if there’s a way for me to fix this frequency problem on my own as I should not have to spend 30 dollars to fix this again when neither my phone maker or service provider will help me in the slightest. — Kristian

Solution: Hi Kristian. We don’t know what you mean exactly by the “frequency problem” you’re referring here but we assume the person who fixed your device tweaked the software. Technically, if we say a device is not compatible with a network’s frequency, that’s because a phone’s radio can only work with limited frequency bands. You can’t just change the operating frequency bands of a device to make it compatible with the frequencies of a certain network.

As much as we would like to help you, there’s nothing much that we can do about your issue. You must let a technician physically check the device so he or she can determine what software changes needs to be done.

I have a Samsung Galaxy S7 and have never had issues until this last month. It is very slow to respond when opening messages from text or messenger. Videos won’t play through and keep pausing and I have to keep pressing play again. Sometimes keyboard stays on screen longer than messages screen so have half keyboard/ half home screen showing. I currently run 360 security app on my phone but have been told I don’t need this or any antivirus, is this true? Help please. — Jessedwards

Solution: Hi Jessedwards. Instead of fixing issues individually, we suggest that you do a factory reset instead to try and fix all of them. To see if a problematic app is to blame, you also want to make sure that you don’t re-install apps right away after a factory reset. This will allow you to check if there’s a difference when the phone only runs a clean version of Android and when there are apps installed. To factory reset your S7, follow these steps:

Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.

Turn off your Samsung Galaxy S7.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’

Once highlighted, you may press the Power key to select it.

Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.

Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

The phone will now reboot longer than usual.

Problem 7: Galaxy S7 stuck in endless boot loop

The phone is stuck in an endless loop of restarting and then getting stuck on the Samsung logo. I have tried everything on your blog related to this but this isn’t going away. If I press the volume down key after the Samsung logo appears out just restarts.. Doesn’t move into the android logo but gets stuck again. Can you please help? — Tejraj P

Solution: Hi Tejraj P. Please see our suggestion for Antonio above. If the phone won’t respond or remains stuck in boot loop, there must be a hardware problem causing it. In that case, have the phone repaired and replaced.

Problem 8: Galaxy S5 and S7 incoming calls are being diverted to voicemail

My partner has a Samsung Galaxy S5 and I have a brand new S7. We both have the same problem. We are with Plusnet and when we are set to connect automatically to 2G/3G & 4G our phones will not receive phone calls but go straight to voicemail. — Lorraine.braddon

Solution: Hi Lorraine.braddon. This is an issue that only your carrier can fix so we suggest that you let them know of this issue as soon as possible. There must be some misconfiguration in the device or in your account that forces incoming calls to your voicemail.

In some cases, users may forget that they may have enabled call divert feature on their number. Be sure to talk to your carrier technical support team about it so they can walk you through how to check it.

Problem 9: Galaxy S7 speaker volume is low during calls

I bought a phone on eBay. Finally got it to connect to our wifi and it seems to work OK but I can barely hear the caller when I receive calls. I’ve tried increasing volume but that just makes the ringtone etc louder. I’m not super technical. My brother says “aol” stands for all old ladies… Can this be fixed? I’d appreciate any help. Thanks. — Ashley

Solution: Hi Ashley. If the volume problem only occurs during calls but not in other functions that require the loudspeaker such as when playing music or videos, then the reason must be on the software side. Try to use a different app for calls like Facebook Messenger or Google Hangouts. There are a ton of other similar apps in Google Play Store so take your time in testing them out. If the problem persist after using multiple apps, consider doing a factory reset. Refer to the steps above on how to do it.

On the other hand, if said problem happens whether you’re in a call or not, it’s probably due to a faulty hardware, particularly a malfunctioning loudspeaker. As a workaround, you can try using a wired or wireless headset during calls. If you don’t want that, have the phone replaced.

Problem 10: Galaxy S7 screen flickers when brightness is set to low

Hello! I have a Samsung Galaxy S7 and lately whenever i turn the phone brightness lower than halfway up the bottom 1/3 of the screen flickers. The flickering persists in any app and I’ve tried soft resetting. what might this be? — Matt p.

Solution: Hi Matt p. An issue like this is usually caused by bad hardware. Try a factory reset and see what happens after that. If the problem stays, get a phone replacement.
